Title: The Emerging Potential of Earth Observation for Coastal Waters


Abstract: The availability of public satellite imagery, combined with advanced image interrogation and cloud computing, triggered an unprecedented flow of information relevant to the coastal engineering and research community. From satellite imagery we can nowadays for example derive subtidal bathymetry, beach slopes, beach sediment types and coastline dynamics, at accuracies that increasingly allow for engineering applications. The high spatial and temporal resolution of this information yields more comprehensive understanding of our coasts and its dynamics. This is not only of great added value in data-poor environments, it will also allow for more cost-effective coastal monitoring in data rich environments as the necessity of in-situ measurements will reduce in future. The talk will discuss the different methods and cases, with the aim to increase the level of understanding of the behavior of the world’s beaches to better support assessments on the effects of climate change.
